The geometry of bipartite qutrits including bound entanglement
- 1. Fakultaet fuer Physik, Universitaet Wien, Boltzmanngasse 5, A-1090 Vienna (Austria)
Description
We investigate the state space of bipartite qutrits, in particular we construct an analog to the 'magic' tetrahedron for bipartite qubits-a magic simplex W. Due to the high symmetry it is enough to consider certain typical slices through W and optimal entanglement witnesses can be calculated. A whole region of bound entangled states is found
